to roll out the trial before the incident. In the end of 2000, Robert Edward Dyer made a similar attempt at extortion involving Clubcards with a magnetic strip for ATM withdrawals. Dyer sent several letter bombs, one of which exploded when the recipient opened it, before being arrested in February 2001. David Sainsbury, then chairman of J Sainsbury plc, rejected the idea of introducing a similar scheme. However, the effect that Clubcard had on Sainsbury's sales led to the reversal of that decision, with the launch of the Sainsbury's Reward Card in June 1996. After two slight amendments to the design of cards in the 1990s by Evans Hunt Scott's creative team, the scheme had a major relaunch in 2005 with all members being sent personalised cards and key fobs which could be scanned at the checkout, rather than swiped. The scheme was again relaunched in 2008 with all seven million members once again being sent new design cards and key fobs. A further redesign in 2017 allowed contactless technology to be embedded in the cards and key fobs. Abroad The Tesco Clubcard scheme was introduced into the Republic of Ireland almost immediately after Tesco's acquisition of Power Supermarkets Limited (now Tesco Ireland), and operates in similar fashion. It was originally an extension of the scheme in the United Kingdom, not a separate scheme, so Irish Clubcards could be used in stores in the United Kingdom until 2019. In 2007, Tesco Clubcard was first introduced in all Tesco Extra stores in Malaysia and later in all store formats. In Malaysia, every two Ringgit spent earn 1 Clubcard point. By 2014 the scheme had 1.7m cardholders. The Tesco Clubcard scheme was introduced into Polish Tesco Stores in 2008, and Slovakia at the end of 2009. As of September 2010, these markets had 1.5m and 850,000 cardholders respectively. Though operating in a similar fashion to the scheme in the United Kingdom, it is independent, so Clubcards from other countries cannot be used in Slovakian or Polish stores. In Slovakia every €1 spent gives 1 Clubcard point (or one point per litre of petrol). Clubcard was launched in the Czech Republic and Hungary in 2010. Benefits When shopping at Tesco or using Tesco services (such as services from Tesco Bank), Clubcard holders receive points based on the amount spent. For shopping at Tesco they receive one point for every £1 (one point for
